Answer: Figure 2.
Explanation:
Suppose that we have an angle with measure ∠M, a bisector would be a line that divides this angle in two equal parts, such that each new angle has measures (∠M)/2
Then the correct option will be the one that has two equal angles.
In figure 2, we can see that RP divides the angle SRQ in two angles 52°, then RP is the bisector of the angle.
Then the correct option is figure 2.
